A Class B Glass Burette with a PTFE Stopcock is the standard choice for general laboratory titrations where high precision is required but formal certification is not necessary. It combines the chemical resistance of borosilicate glass with the convenience of a maintenance-free valve.

Key Features

  • PTFE Stopcock (Key): Unlike glass keys, PTFE is self-lubricating and grease-free. This prevents "frozen" valves and ensures your samples aren't contaminated by stopcock grease.
  • Class B Accuracy: Offers a standard tolerance (e.g., ±0.10 mL for a 50mL unit), which is twice that of Class A but perfectly suitable for most educational and routine industrial tests.
  • Material: Built from Borosilicate 3.3 glass, making it highly resistant to acids, alkalis, and thermal shock.
  • Graduations: Usually features permanent, easy-to-read blue or white enamel markings.
